Men with impaired glucose tolerance have lower self-rated health than men with impaired fasting glucose

Abstract

AimPrevious studies have shown that individuals with impaired glucose tolerance (IGT) have lower self-rated health than normoglycaemic individuals. The aim of this study was to examine differences in self-rated health between individuals with IGT and those with impaired fasting glucose (IFG) and to consider the potentially mediating effect of physical activity. MethodsIn 2002–2005, a total of 2816 individuals were randomly selected for a population-based study in Sweden. All participants performed an oral glucose tolerance test (OGTT). Fasting venous blood samples were drawn, and questionnaires concerning lifestyles were completed. Self-rated health (SRH) and leisure time physical activity (LTPA) were reported on a five-graded and four-graded scale, respectively. A total of 213 individuals with IGT and 129 with IFG were detected. ResultsIGT, but not IFG, was associated with low self-rated health. The difference in self-rated health was seen particularly in men when adjusted for age and BMI (OR = 2.13, CI: 1.13–4.02, p = 0.020). The results became insignificant when including physical activity in the model (OR = 1.8, CI: 0.91–3.58, p = 0.094). ConclusionThe low self-rated health adds further weight to the risk profile in men with IGT and stresses the importance of early detection and lifestyle interventions.
